Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header. 2020-01-18 05:38:21 -03:00			`/*`
LibC+LibELF: Implement more fully-features dlfcn functionality This implements more of the dlfcn functionality. Most notably: * It's now possible to dlopen() libraries which were already loaded at program startup time. This does not cause those libraries to be loaded twice. * Errors are reported via dlerror() rather than by crashing the program. * Calls to the dl*() functions are thread-safe. 2021-04-24 15:39:58 -03:00			`* Copyright (c) 2021, Gunnar Beutner <gunnar@beutner.name>`

Everything: Move to SPDX license identifiers in all files. SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt * 2021-04-22 05:24:48 -03:00			`* SPDX-License-Identifier: BSD-2-Clause`
